ISAAC WANTLING, OF PEORIA, ILLINOIS, ASSIGNOR TO WANTLINGS FAVORITE OOAL DRILL COMPANY, OF PEORIA, ILLINOIS, A COR- PORATION OF ILLINOIS.

COAL OR ROCK DRILL.

SPECIFICATION forming part of Letters Patent No. 740,720, dated October 6, 1903. Application filed AugustZZ, 1902. Serial-No. 120,671. (No 11101121.).

To all whom it may concern:

Be it known that I, ISAAC WANTLING,a citizen of the United States, residing at Peoria,

in the county ofPeoria and State of Illinois,

- rock drills.

More particularly,the invention relates to an improvement upon the drills illustrated and described in Letters Patent N 0. 678,845, dated July 16, 1901; No. 683, 158,dated September 24, 1901, and No. 683,628, dated October 1, 1901, issued to me; and the object of the present invention is to provide a drill of a support comprising two standards joined in common castings at their upper and lower ends and in such a manner as to prevent vertical or lateral displacement, the lower castin g having an extended portion of considerable length with a central aperture, through which is carried an adjustable shoe, also of considerable length.

A further object of the invention is ayoke having two sockets adapted to the standards of the drill and provided with extensions for supporting the boxings for a drill-rod and its operative parts, the arrangement of the yokesupport for said boxing being such that the boxing and drill parts may be raised and lowered on the standards and the drill-rod swunginto a vertical, horizontal, or other desired positions and the standard and drill ports moved into positions, as will become apparent, heretofore not made possible in drills of thisclass.

To these ends my invention consists in the novel features and in the construction and arrangement of parts hereinafter fully described, and definitely pointed out in the appended claims following the description, due reference being had to the accompanying drawings, forming a part of this specification, in which-- position.

. Figure 1 is a perspective view illustrating my complete drill. Fig. 2 is an enlarged side elevation of the support, the yoke and boxin g shown supported thereby, the boxing also shown in dotted lines swung into a vertical Fig. 3 is a front elevation of Fig. 2' with the boxing shown in crosssection. Fig. 4 is an-elevation similarto Fig.2 with the standard swung around and the boxing supported in a position opposite to that in Fig. 2, the boxing also provided with a flared extension whereby it may be looked in adjusted positions. Fig. 5 is a vertical crosssection of the lower end of the standards and the adjustable supports therefor.

Referring to the figures, 1 1 indicate standards or post-supports for the operative parts of a drill. They appear substantially rectangularin cross-section and are joined in common castings or cross-braces 2 and 3 at their upper and lower ends,respectively. The brace 2 has the face plates 4 engaging the inner faces of the standards and lap over the edges, as shown, and the upper ends of the standards are seated in sockets formed by the overlapping end portions 5'of the brace, and the said brace is riveted or otherwise suitably secured tothe standard. The brace is further provided with a vertical bearing 6, through which is carried a threaded spindle 7, ar-

of the coal or rock being drilled.

Beferrin g to the brace 3 at the lower end of the standards for connecting the lower ends of the standards, the same is provided with the face-plates 8 engaging the inner faces of the standards andlapover the edges, and the ends of the standards are seated in'sockets 9, formed by the overlapping end portions 10,and 11 is a rectangular extension integral with the brace 3, of considerable. length, depending from the brace, and with the shortupper extension 12 of the part 11.

13 indicates a shoe in cross-section, substanranged for positive engagement with the wall tially an I-beam, adj ustably carried through 5 the part 11 and fixed in the adjusted positions by a pin 14, carried through the part 11, and a boss 15, and adapted to engage depressions 16 in the body of the shoe 13, although these depressions may be dispensed with if desired,

as they are not essential. The brace 3 is secured to the standards by being riveted or otherwise secured thereto, and the function of the extension 11 and the shoe 13 will be further described.

17 indicates ayoke of a casting, comprising the rectangular hollow body parts 18, adapted to the standards 1 to slide up and down thereon, and 19 is a boss through which a threaded pin 20 is carried to engage the face of one of the standards for adjusting the yoke 17 at different heights on the standard. The rectangular body portions are joined by a web 21, hav ing oppositely-curved faces 22. Extending forwardly and upwardly from each of the body parts and also downwardly therefrom are shown ears or extensions 23, each provided with the perforations 24, lying in the same vertical line,and represents centrally-disposed ears or extensions extending forwardly from the body parts 18, with perforations 26 in the same vertical line with perforations 24: in the ears 23, and the said cars 25 are displaced inwardly and slightly out of vertical line with the ears 23 and are connected therewith by the webs 27.

28 refers to a two-part hinged boxing having the nut portion 29, and 30 is a threaded drillrod passing through said boxing and engaging the nut 29 therein. The boxing is provided with an extended body part 31, having an aperture 32. The boxingherein is similar in construction throughout to the boxings in the patents above referred, to. In Fig. i the boxing has the flared portion 33, provided with a series of apertures or semicircular serrations 34:,

which lie in an arc of a circle struck from the aperture 32. It is desired to support the boxing between the cars 23 of the yoke 17, and a pin 35 is employed for supporting the boxing on the yoke by passing it through the aperture in the ear 23 and the aperture in the boxing. For supporting a boxing like that shown in Fig. 4: a yoke-pin 35 is employed, having the parts 36 and 37, which will pass, respectively,

through the ears 23 and 25 and engaging the aperture 32 and a serration in the extension 33, adapting the boxing to be swung on its support and locked in different positions. Thus the function of the ears or extensions 23 and 25 are readily apparent.

In this present invention I have provided for not only supporting the boxing to enable the same to be raised or lowered on the standards 1, but have provided a support whereby the boxing may be swung in any angle from vertical to horizontal, or vice versa, and have constructed the support in such a manner that the standard may be turned upside down and the boxing rearranged for operating the drill when the standards are in such reverse position and have provided further adjustment, which will be described.

It will be seen without further explanation that by reason of the extensions of the yoke the support of the boxing is such that it may be swung into the positions above suggested.

If it should occur, and it often happens,

that in fixing the standards 1 preparatory to setting the drill-rod and boxing in an opening it is found that to place the boxing in the position shown in Fig. 2 the auger is longer than the distance from the boxing to the wall of the out where it is desired to drill, the standards may be swung so that the yoke 17 will be in the position shown in Fig. 4, which is just opposite to that shown in Fig. 2, when the boxing will be placed similar to that shown in Fig. 2, but with the main body and forward portion thereof extending between the standards, as shown. Ordinarily in placing the drill if the distance is, as above suggested, between the boxing and wall of the cut it is generally such that by moving the standards from four to six inches it is sufficient, but this resetting of the standards is obviated by the construction of the boxingsupport, where by the standard may be swung and the boxing adjusted as in Fig. 1.

Referring again to the brace 3 and the extension 11, which is of considerable length, it will be seen that the standard may be fixed in cuts or openings of considerable height and at the same time the drill operated in cuts or openings that will carry as small a drillthat is, in height-as any drill now offered to the trade. As the shoe represented in the drawings is approximately twenty-two inches in length and by reason of the extension through which it is carried, which is also of considerable length, the opening in which the extension may be carried is readily apparent and by reason of the sockets in the braces 2 and 3, in which the upper and lower ends of the standards are seated, the same are assured an additional brace, as will be seen from an examination of Fig. 5 of the drawings, and by reason of the extension 11 and the shoe 13, which are both of considerable length, as has been suggested, it ofttimes happens that the boxing cannot be placed low enough on the standards 13, and

it is necessary to swing the standards so that the threaded spindle 7 will be caused to engage the floor of the cut or opening and the shoe 13 the ceiling, when the boxing may be adjusted in as low a position as any similar drill, and thus the reversibility and practical utility of the oppositely-disposed ears 23 of the yoke 17, which enables me to place the boxing whether the standards are in the position shown in Fig. 1 or in a position opposite thereto, will be readily seen.

A further object of the depending extension 11 from the lower end of the post is to give to the post any reasonable length under Varying conditions by using only one length shoe. This rectangular extension or depending body acts not only as an additional support for the shoe and the post, but is an extension itself,

I for it is the practice in machines of this character, when wishing to extend the height of the post to a greater distance than that attained by the use of an ordinary shoe, to employ two shoes and make two joints at the base of the post, whereas by providing such an extension as I show, which is of considerable length, I need only employ one shoe, making the shoe of an I-beam. The support for the post is more substantial and is a saving in weight and construction, and whereas it has been necessary when using an additional shoe for extending the post to use two locking-points, one with the base and the other with the shoe which weakens the support, I only use one.

The drill-rod 30 has shown attached thereto the auger 38 and carries the bevel-gear 39. meshing with the bevel-pinion 40, operatively carried by the boxing 4-1, which forms a part of the boxing 28, and 4:2 is a crank whereby the said gears may be actuated for operating the drill-rod 30 for the purposes herein. a

I wish to call particular attention to the fact that the boxing herein employed is void of trunnions or studs commonly employed and integral with boxings of this class, and the support for such a boxing carried by the standards have loops or sockets in which the trunnions or studs are dropped, which in some instances necessitate the standards being farther apart than is necessary in my drill, and it is to be especially noted that the form of support herein employed with perforated extensions to adapt them with a boxing with a transverse aperture, instead of the trunnion heretofore used, which is not practical with this form of support, will prevent the boxing from dropping out of .its support when the drill is turned upside down, and in addition by the provision of the means whereby the standards may be extended or shortened or turned upside down the boxing may be attached or detached and replaced when the standard is upside down by the provision of an extension of the member 17, as suggested.
